RAILROAD-RAIL.

Specification of Letters Patent.

Patented May 14, 1907.

Application filed June 23, 1906. Serial No. 322.991.

To afl/f w/I/om 'llt may concern,.-

Be it known that I, WILLIAM G. MAC- LAUGHLIN, a citizen of the United States, residing at Walkerville, county of Essex, Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Railroad-Rails, of which the following is a specification, `reference being had therein to the accompanying drawings, in which- Figure 1 is a perspective sectional view; Fig. 2 a sectional view showing a slightly different form of rail 5 Fig. 3 a detail plan view showing the abutting ends of two base sections; and Fig. 4 a detail plan view of one end of a base section of a slightly different form.

One ofthe many objects of this invention is to provide a railroad rail of the girder type in which the tread or ball of the railis a separate piece and is supported by the base section of the rail, said tread section being provided with a longitudinal depending web which fits within a corresponding channel in the base piece. 4The girder section consists of a permanent support which may be either bolted to or formed integral with the base piece, and a removable upper wearing section which is locked in place by the tread section. The base section of the rail is formed of coinparatively soft steel while the ball or tread section is formed of hard steel to withstand the wear of the car wheels. The supporting member of the girder section is formed of comparatively soft steel while the wearing section is formed of hard steel. It will, therefore, be seen that that portion of the rail which must withstand wear is of the ,o usual hard rail steel and that these hard sections are supported on comparatively soft steel. rlhe object of thus forming the rail sections of different qualities of steel areto reduce the expense of manufacture and to prevent the rails breaking under the usual strains brought on them. Should the hard tread section fracture, the soft base section will hold the portions of the tread section rigidly in position;

Referring to the various parts by numerals, l designates the base section of the rail which is'provided with the two upwardly extending longitudinal supporting members 2 which are located a slight distance apart to form a central channel 3. The tread section 4 of the rail is provided with a central longitudinal web or tongue 5 which exactly fits the central channel 3 formed between the supporting members 2.\ The head of the tread section is formed with the longitudinal grooves 6 in its under side to receive the upper edges of the supporting members 2, and the said head of the tread section projects laterally slightly beyond the outer surfaces of said supporting members. The base section l is formed of comparatively soft steel so that it will not fracture under the strain brought upon it; while the tread section 4 is formed of hard steel to withstand the wear and strain of the car wheels. It will be noted that should the hard tread section 4 become fractured, the pieces thereof will b e securely held in position by the supporting members 2.

The supporting members 2 of the base section are formed on their inner surfaces with comparatively broad longitudinal grooves 22L which are adapted to receive electrical conductors. On one of these members below the grooves 2a therein is formed a second longitudinal groove 2b which is adapted to receive an electrical conductor, such as a telephone wire. These conductor-receiving grooves are thus formed in the supporting members in order that they will be protected from the depending web 5 of the tread portion of the rail, and also so that said web may be withdrawn from the channel 3 without disturbing the electrical conductors.

Secured to, or formed integral with, the basesection, and. extending outward from one of the supporting webs 2 is a girder section support 7 which inclines upward and outward and is formed at its outer end with the horizontal portion 8. On the upper side of this horizontal portion is formed a rib 9 which extends the entire length of the girder section. Supported on this girder section 7 ofthe rail is a wearing member l0. This member 10 is formed in its under side with a groove 11 to receive rib 9,'and its inner lower end extends under the projecting portion of the tread, said tread forming a locking means to hold this upper member of the girder section in position. It will be noted that this wearing member of the girder rests at its inner edge against the side of the adjacent supporting member 2. By this means this wearing member of the girder will be rigidlyV held in place without the necessity of bolting it, or using any other form of securing means.

The ends of the adjoining lengths of the base section abut together squarely as shown in Fig. 3, said ends being supported upon a IOO IIO

rigid foundation or base 12.. The tread portion of the rail is placed on the base portion in such manner as to break `joints therewith.

By Iforming the tread portion 4 with the grooves 6 to receive the upper ends of the g supporting members 2, and extending the said tread -portion laterally beyond the sides of said supporting members, said tread portion will prevent anyspreading of the supporting members. it will be readily seen that said supporting members cannot be spread by any downward strain brought on the tread portion and that, therefore, the base and tread sections are eiliectually interlocked.

In the form of the device shown in Fig. 2, the base section is formed of two pieces A and B, one sup] orting member 2 being formed on each piece and the joint between the two pieces being along the longitudinal center line of the rail. In this form of the rail the girder section@ is horizontal instead. of inclining upward and outward as shown in Fig. 1 and carries the wearing member C. The two parts A-B of the base section may be secured. together by bolts A as indicated in .F ig. 2 of' the drawings. The ends of the base section may be shouldered-as shown at 13 in plan view in Fig. 4, so that the abutting ends oi' adjoining base sections will be interlocked.

From the foregoing it will be readily seen that both the tread section and the wearing section. of the girder may be renewed whenever they become worn or breken without the necessity of unspiking the rails from the ties. As the tread portion of the rail and the wearing portion of the girder section are not bolted in place they may be removed and new ones replaced 'with little diliculty. It will also be noted that tbe tread section may be reversed as to its position on the base section 'whenever it becomes worn along its inner edge, without disturbing the girder portion.

Having fully described my invention, what .l claim as new and desire to secure by Letters Patent is 2- 1. A girder rail comprising a base section, a tread section supported by the base section, and a girder portion extending outward from the base section and consisting of a permanent part rigidly connected to the base section, and an upper wearing part removably secured to said permanent part.

2. A girder rail comprising a base section,

a tread section, and a girder section, this lat- I l ter section being formed of a permanent portion and a removable wearing portion, the latter portion heilig locked in position by the treadv portion.

3. A girder rail comprising a base section. l a treadv section, and a girder section consistj ing of a permanent portion and a removable wearing portion, and means i'or locking said removable section in position.

4. A railroad rail comprising a base section formed in two Apieces adapted to llit together along the longitudinal line oiY the rail, each ol' said pieces being iormed. with an upward extending` supporting member` and a tread seetion provided with a depemling l lange adapt ed to lit between the supporting members ol the base section and with an overlapping part adapted to engage the upper ends olx the supporting members and to prevent the lateral spreading thereof, and a girder section carried by one of' the base pieces.

5. A railroad rail comprising a base section formed with upward extending supporting members 'separated a suitable distance to form a central longitudinal channel, a tread section formed with a depending longitudinal web and. adapted to lit closely between the supporting members, and a girder portion extending outward Vlrom the base section and consisting of a permanent part rigidly connected to the base section, and an upper wearing part removably secured to said permanent part.

6. railroad rail comprising a base section formed with upward extending supporting ,members separated a suitable distance lo 3 'form a central longitudinal channel, said supporting members being provided with longitudinal grooves on their inner surlaees adapted to receive electrical eomluctors, a tread section formed with a. depending longitudinal web adapted to lit closely between the supporting members and to hold the eleetrical conductors in the grooves in the supporting members, and a girder portion extending outward irom the base section and consisting of a permanent part rigidly connected to the base section, and an upper wearing part removably secured to said 'permanent part.

In testimony whereol" .l hereunto al lix my signature in the presence oiE two witnesses this 12 day of June 1906.
